Blue Ivy Helps Beyonce Celebrate 31st Birthday — Pics

The ‘Single Ladies’ singer and husband Jay-Z enjoyed a Mediterranean cruise on their yacht with 7-month-old daughter Blue Ivy to celebrate Beyonce’s birthday! This is the first time we’ve seen baby Blue’s adorable face since she was born — she’s grown up so much!

Beyonce was happy and relaxed as she rang in her big 3-1 with a low-key day at sea. The birthday girl made sure to have her post precious gift with her — daughter Blue Ivy Carter!

Instead of throwing a lavish, star-studded party, the A-list pair decided to keep Beyonce’s birthday intimate and family-focused — the superstar singer even went without makeup!

Doting dad Jay-Z was spotted holding his little daughter and playing around with her on deck. He also decorated their yacht with balloons and streamers to celebrate his lady’s special day!

Although Blue Ivy is only seven months old (she turns eight months on Sept. 7), she has quite the head of hair.
